There were tears and laughter yesterday at an emotional double funeral service for a Long Island teacher and his student killed in a van crash during a class trip in Arizona.

More than 1,300 family members, classmates and friends filled the auditorium of Chaminade HS in Mineola and another 300 mourners outside participated in the 10 a.m. funeral Mass for student Brendan Tracey, 16, of Garden City and Brother Lawrence Zarzycki, 38.

“This is the Chaminade family,” said school president Father James Williams in his eulogy. “This is my family and I am so proud to claim that.”

Williams said Zarzycki “has spent the past 20 years giving to God, doing it for others by teaching, by feeding the poor, by loving the lonely, by serving his fellow brothers.

“Lawrence loved music,” he said, “although some of his students, this one included, would question his tastes. He liked the Carpenters, especially the song ‘Close to You.'”

Mourners with tears in their eyes broke out in laughter.

Zarzycki fed his students “with food or knowledge. He loved and cared for them,” said Williams.

Tracey, about to start his junior year at the 70-year-old Catholic boys school, spent long hours at the school’s yearbook office, where he was an editor, in practice with the volleyball or swimming teams, or in volunteer work to help the poor.

“His mom would jest of his time at Chaminade, ‘He attends a boarding school.’ Oh, he was so loved. Oh, they were so loved,” said Williams, who noted that Chaminade students are called Flyers.

“Brendan and Brother Lawrence are with the Lord, close to him. We will fly like the eagle. The Flyers will soar as long as you remain with the Lord,” Williams said.

Police in Arizona said fatigue may have played a role in the accident Saturday as the group of students and brothers was traveling in a van to the Grand Canyon.

Zarzycki was at the wheel when he veered off the road and then over-compensated – flipping the van. Zarzycki and Tracey were killed instantly. Two other students suffered minor injuries.
